Where industrialization is occurring_________ , while where there is no
industrialization, _________.
a. infections and allergies are on the rise; infections and allergies are less developed
b. obesity is reduced; malnutrition does not exist
c. infections and allergies are less developed; infections and allergies are on the rise

What are the three observations of natural selection?
a. Species change and adapt based on environmental pressure, individuals change
within their lifetime, and offspring inherit the changes.
b. Genetic drift, gene flow, and mutations provide the change necessary in populations
that affect future generations.
c. Organisms produce more offspring than survive, populations vary, and traits are
inherited.
d. The number of adults tends to remain the same over time, inheritance provides all of
the genetic variation needed for future generations, and natural selection works on only
the best of those adults in each generation.
A hominid fossil that has a long, low skull, projecting face and occipital bone, and large
nasal aperture is likely:
a. to be classified as having modern characteristics.
b. to be classified as having australopithecine characteristics.
c. to be classified as having archaic characteristics.
d. to be classified as having apelike characteristics.

a. the transfer of pathogens from other animals to humans.
b. the transfer of genes from other animals to humans.
c. a gene pool of nonhuman genes only.
d. the phenomenon of genetic change in nonhuman species.
You are reading a scientific paper regarding the relationships of the anatomical and
behavioral characteristics of chimpanzees and their implications for early hominid
evolution. You note that the authors refer to human ancestors as hominids. This implies
that:
a. the researchers are relying on genetic classifications of chimpanzees and humans, as
this is most appropriate for their research.
b. the researchers are relying on anatomical classifications of chimpanzees and humans,
as this is most appropriate when looking at adaptation and anatomy.
c. the researchers are relying on genetic classification of chimpanzees and humans,
hence their use of the term "hominid" to describe human ancestors.
d. both b. and c.
Homo erectus's cranial capacity:
a. is always less than 1,000 cc.
b. is always more than 800 cc.
c. ranges from 650 cc to 1,200 cc.
d. ranges from 900 cc to 1,200 cc.
A genetic study conducted over two generations found that the frequencies of genotypes
in the first generation were AA: 0.36, Aa: 0.48, aa: 0.16. In the second generation,
genotype frequencies remained the same. According to Hardy-Weinberg equilibrium,
we can assume:
a. negative assortative mating has maintained gene frequencies.
b. mutations have likely occurred, resulting in the same frequency.
c. mating in this population is random.
d. the population is small and we cannot detect change.

Stratigraphic correlation is:
a. matching strata by chemical composition and color from several sites across
distances.
